DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a charging section support base for supporting and fixing a charging section such as a main bar in a distribution board to a panel.

[0002]

2. Description of the Related Art Conventionally, a mounting structure for mounting a charging section support base for supporting and fixing a charging section such as a main bar in a distribution board to a panel has been as shown in FIGS . That is, the rail 3 is provided inside the box body 32 of the distribution board 31.
Panels 34, 35, 36, 37, 38, 39 are attached between the rails 33, 33, and a main breaker 41 mounted and fixed on the panel 40 is attached to the panels 34, 35. A main bar 42a, 42b, 4 formed in a substantially L-shape at the secondary terminal of the main breaker 41.
2c is connected. On the other hand, panels 36, 37, 38, 39 are mounted between the rails 33, 33, and the branch breakers 43, 43, 43, 43 are mounted and fixed thereto. Each branch breaker 43, 43, 43, 43 has a main bar 42a,
Branch bars 44a, 44b, 4 connected to 42b, 42c
4c. The main bars 42a, 42b, and 42c are supported and fixed by a charging unit support 46 mounted and fixed on a panel 45 attached to the rail 33. Wearing is fixed.

[0003]

However, in the above-mentioned conventional distribution board 31, since both ends of the charging section support base 46 are fixedly screwed on the panel 45 with screws 47, 47, the charging section support board 46 is fixed. When the rail 33 is disposed immediately below the screw portion of the base 46, the rail 33 may be an obstacle and cannot be screwed.
There is a drawback that special processing for mounting 7 must be performed.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional distribution board, an object of the present invention is to provide a special processing for an obstacle even if there is an obstacle immediately below a screw portion of a charging section support base. By providing a distribution board that can attach the charging unit support stand without performing, at least rails are juxtaposed inside the box body, a panel is attached between the rails, and a main breaker on the panel, A branch breaker for branching power from the main breaker and supplying it to each load circuit, a main bar connecting between the main breaker and the branch breaker, a branch bar connected to the main bar, An upper surface of a side wall is formed in a substantially U-shape on at least one of mounting portions for mounting the charging portion support to the panel, in a distribution board configured with a charging portion support that supports and fixes the main bar . the provided engagement flange portion, said The panel provided with a locking portion which is substantially U-shaped side wall and the locking of the charging unit support base of the locking collar portion, engaging portion and the charging unit support base of the locking flange portion substantially U-shaped Is formed to be lockable with the side wall.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A substantially U-shaped side wall of a locking flange provided at one end of a mounting portion of a charging portion support stand and a locking portion of a panel are locked, and the other end is provided. Is fixed with screws .
The charging part support base 16 is securely paneled with only one screw 19.
Attached to. After that, to support and fix the main trunk bar.

[0006]

1 to 4 show an embodiment of a distribution board according to the present invention .
Shown in Hereinafter, the present invention will be described with reference to these drawings.

Rails 3 are provided inside box body 2 of distribution board 1.
3 are arranged side by side, and panels 4, 5,
Attach 6,7,8,9 and panel 10 to panel
A main breaker 11 mounted and fixed on the main breaker 11 is attached, and main bars 12a, 12b, and 12c formed in a substantially L shape are connected to secondary terminals of the main breaker 11. On the other hand, panels 6, 7, 8, 9 are mounted between the rails 3, 3, and the branch breakers 13, 13, 13, 13 are mounted and fixed to these panels. The branch bars 14 connected to the main bars 12a, 12b, 12c are connected to the respective branch breakers 13, 13, 13, 13.
a, 14b and 14c are connected. Main bars 12a, 12
b and 12c are supported and fixed by a charging section support 16 mounted and fixed on a panel 15 mounted on the rail 3, and at least one of the mounting sections for mounting the charging section support 16 to the panel 15 has side walls. The upper surface is formed in a substantially U shape
The locking flange 17 is provided, and the panel 15 is provided with a locking portion 18 for locking to the substantially U-shaped side wall of the locking flange 17 of the charging section support base 16 .

According to the distribution board 1 having this structure, the substantially U-shaped side wall of the locking flange 17 provided at one end of the mounting portion of the charging portion support base 16 and the locking portion of the panel 15 18 and the other end is screwed and fixed with a screw 19 , the charging portion support
Holder 16 is securely attached to panel with only one screw 19
Be killed. As after, trunk bars 12a, 12b, and 12c is supported and fixed.

The shapes of the locking flange 17 and the locking portion 18 that locks the locking flange 17 are not limited to the present embodiment, but can be changed as appropriate without departing from the spirit of the present invention.

[0010]

As described above, in the distribution board according to the present invention, at least rails are juxtaposed inside the box body, panels are attached between the rails, and the main breaker and the main breaker are mounted on the panels. A branch breaker for branching the power supply from and supplying the load to each load circuit, a main bar connecting the main breaker and the branch breaker, a branch bar connected to the main bar, and the main bar. in distribution board which is composed of a charging unit supporting base for supporting the fixed upper surface of the side wall on at least one of the mounting portion for mounting the charging unit support base to the panel is formed in a substantially U-shaped engagement flange the section provided, said panel engaging portion of substantially U-shaped side wall and the locking of the charging unit support base of the locking collar portion provided in the charging unit support base engaging Tometsuba portion and locking portion The U-shaped side wall of the Accordingly, there is an effect that it is possible to attach the charging unit supporting base without performing special processing on the obstacle even if an obstacle directly under the charging unit supporting base of the mounting portion. Further, since the number of places to be screwed with screws can be reduced, the time required for assembling the distribution board can be reduced, and the charging section support base can be more firmly fixed.
